Bighorn Web Solutions LLC Reviews & Testimonials
Jessica Grant Ecommerce Director at Sports Basement
5.0★
Shopify Plus eCommerce Review from Jessica Grant
Bighorn has been an exceptional partner to our organization here at Sports Basement. They supported us through multiple legal and regulatory accessibility matters with a steady, knowledgeable approach, translating complex requirements into clear, actionable guidance. Throughout these engagements, their team demonstrated a strong understanding of both the legal landscape and the practical realities of building and maintaining accessible digital experiences, which gave us confidence at every step.What truly distinguishes them is that their work goes well beyond compliance. In addition to helping us identify and prioritize accessibility issues, they invested time in educating our teams on how to design and develop accessibility into our site from the start. Their recommendations are thoughtful, pragmatic, and focused on real user impact, enabling us to move from a reactive posture to a more proactive, sustainable accessibility practice.Most importantly, they operate as true partners rather than transactional consultants. Their work is clearly driven by a genuine commitment to making the web usable by all, not simply meeting minimum standards or checking a box. We would strongly recommend them to any organization looking for a strategic accessibility partner who combines expertise, integrity, and a long-term perspective.

AJ Canty CTO and Co-Founder at Primer
5.0★
Web Development Review from AJ Canty
We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

Jutamas Puengpinit Ecommerce Specialist Health & Beauty at Mandom Corporation (Thailand) Limited
5.0★
eCommerce Development Review from Jutamas Puengpinit
We engaged SoftLoft, Inc. to enhance our e-commerce platform, which is critical for delivering our modular IoT solutions efficiently across emerging markets. As Mandom Corporation (Thailand) Limited operates in a fast-paced production and tech environment, we needed a development team that could understand both our industry-specific needs and the technical depth required to support our operations. Our goal was to refine our platform's functionality, improve system stability, and enable easier configuration and ordering of IoT devices for clients.SoftLoft delivered far beyond our expectations. Their team, consisting of a Business Analyst, four Magento developers, and two testers, approached the project with remarkable professionalism. From the outset, the Business Analyst played a pivotal role in capturing our requirements in detail and transforming them into clearly defined tasks. This laid a strong foundation for the developers to implement complex features with precision, and for the QA team to conduct thorough, issue-free testing.The project involved building a new interface for configuring device packages, optimizing backend operations for better order management, and delivering detailed documentation to support ongoing maintenance. Every deliverable was executed with care, on time, and with full transparency.What stood out most was SoftLofts commitment to quality and their responsiveness. Communication was smooth and proactive throughout the project. Their attention to detail, flexibility in accommodating adjustments, and clear documentation ensured a seamless experience for our team. The improvements they implemented significantly reduced internal friction and enhanced client satisfaction.Our experience with SoftLoft was outstanding. They brought structure, clarity, and excellence to every phase of the project. We would highly recommend them to any business seeking a reliable and capable development partner for e-commerce solutions.
Lev Peysekhman Chief Operating Officer at Lane Health
5.0★
eCommerce Development Review from Lev Peysekhman
I had the pleasure of working with this development team on launching an eCommerce store for our healthcare retail business in Thailand. The project was complex building a Magento-based platform integrating over 10 different systems, including product and order management, plus financial tools. They also developed some really smart features, like a dynamic questionnaire that recommends vitamins based on user input, and a secure portal for doctors to manage prescription orders.What impressed me most was their professionalism and adaptability. We had a lot of stakeholders with varying needs, tight deadlines, and even changing regulations that required quick adjustments. Despite all this, the team remained agile, communicated clearly, and delivered exactly what was promised on time.Their technical expertise ensured seamless integration across all systems, which made the entire operation much smoother. Thanks to their work, we launched a fully functional store that improved customer experience and compliance with healthcare regulations. I highly recommend this team to anyone looking for a dependable, skilled partner for complex eCommerce projects.
Rob Duxter Managing Partner at Mynt Partners
4.8★
eCommerce Development Review from Rob Duxter
I'm more than satisfied in my experiences with Soft Loft. I've worked with them for a few years now, on several projects from eCommerce sites (Magento, Shopify, custom) and even apps and information architecture requirements from tech stack evaluation/selection to DNS setup and management. Every team member I've engaged with from their Executives, to Business Analysts to Project Managers, QA and Developers or Information Architects .... total Pros. Whether a small project under $20k or large over $200k - the quality and professionalism is rock solid. Thank you Soft Loft. Keep it up!!
